Your laptop charger has broken or you are looking for another charger for your bag, but you don't know how to choose the right one. For example, how do you know if the charger is compatible with your laptop or has the right power? In this article you will find all the information you need to choose the right charger.
Are chargers with different wattages suitable for your computer ?
The general principle applies in computing that "those who can do more can do less." This means that you can replace a 90 W charger with a 65 W or 45 W laptop charger. However, you must ensure that the voltage value does not differ by more or less than one volt from the original. Check out this site from adapter for advent roma c900 laptop.
Generally, laptop chargers have voltages between 18.5 and 20 volts, so there is no need to worry, but it is still important to be cautious. On the other hand, it is not advisable to use chargers with a voltage lower than that of the laptop. It may work, but since it will be used at full capacity, such a charger can break down quickly. Also, under high load (3D games, video editing, etc.), the computer may stop working due to lack of power and the battery may not recharge even if the device is plugged in.
Finally, the power of the charger should be equal to or greater than the power consumption of the laptop. This is indicated on the label on the bottom of the computer. The power or voltage indicated on the battery should not be taken into account. Ideally, this value should be determined on the original charger, if you still have it.
What about universal chargers ?
There is nothing wrong with using a universal laptop charger, but there are a few things to keep in mind. First, it is best to buy a charger with a minimum power rating of 90 watts. This is because it covers most of the laptops on the market. These models tend to be more expensive, but that is understandable because you can plug them in at multiple points. The disadvantage: safety is not optimal because of the voltage selector switch and removable terminals. So opt for a good quality universal charger costing about 40 euros.
